The Section 27 and Public Domain Books Project houses digitisations (primarily in the form of scans) of books covered by Section 27(1) of New Zealand's Copyright Act 1994 -- that is, many Kiwi court, inquiry, municipal and parliamentary documents.
The Section 27(1)-compliant books themselves thus have no copyright and are provided as e-books on this basis. They're mainly historical texts such as the Mazengarb Report.
On the odd occasion, other (usually related) books that are not Section 27(1)-compliant but in the public domain are scanned and added. Also, the odd set of scanned images donated from Project Gutenberg's Distributed Proofreaders site is uploaded. (Both of these types are clearly marked as such.)
